Add Meson S4 SoC compatible. Yu Tu (5): dt-bindings: serial: meson: Drop legacy compatible. tty: serial: meson: Move request the register region. tty: serial: meson: Using the common clock code describe. tty: serial: meson: Make some bit of the REG5 register writable. tty: serial: meson: Added S4 SOC compatibility. V4 -> V5: Change error format. V3 -> V4: Change CCF to describe the UART baud rate clock as discussed in the email. V2 -> V3: add compatible = "amlogic,meson-gx-uart". Because it must change the DTS before it can be deleted V1 -> V2: Use CCF to describe the UART baud rate clock.Make some changes as discussed in the email Link:https://lore.kernel.org/linux-amlogic/20220110085604.18042-1-yu.tu@amlogic.com/ .../bindings/serial/amlogic,meson-uart.yaml | 10 +- drivers/tty/serial/meson_uart.c | 244 ++++++++++++------ 2 files changed, 177 insertions(+), 77 deletions(-) -- 2.33.1 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
